I can help with 2-plate and 3-plate molds, multi-cavity molds, core & cavity design, sliders, lifters, ejector systems, inserts, runners, gates, cooling channels, parting lines, draft analysis, and DFM optimization.


What you'll get:

  • Complete 3D injection mold design
  • Core & cavity modeling
  • Mold assembly with components
